From the Colton Storm catalogue: "This is a letter in which Audubon denies the charge of a third party that he intended to claim the Quadrupeds, on which Bachman and Audubon were working together, as his work alone. It contains information about the state of the work and is attached to Audubon's manuscript Journal for August to November, 1843." Laid into Copy of my journal from Fort Union (Graff 109).
